Answer:
The factors of given expression are 10+10√2 and 10-10√2.
Step-by-step explanation:
We have given a quadratic expression.
s²-20s-100
We have to find factors of given expression.
We use quadratic formula to find factors.
x = (-b±√b²-4ac) / 2a
From given expression, a = 1 , b = -20 and c = -100
Putting values in above formula, we have
x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)
x = (20±√400+400 ) / 2
x = (20±√800) / 2
x = (20± √400×2) / 2
x = (20±20√2) / 2
x = 10±10√2
Hence, the factors of given expression are 10+10√2 and 10-10√2.
I just took the test i should be 4/33
The expression would be 32+3x where x represents the cost of each shirt. If the shirts were $9 each max would have spent $59
I think it’s .2 I could be wrong but just use a calculator.
Factors are the 'two numbers multiplied' that give you 80. 40 and 2 give you 80, right? So does 20 and 4 & 8 and 10 ............Which means that the only ones that cannot be factors are 80 and 2 because those two multiplied together equal 160.
But of course, all of these numbers individually are factors of 80, but this problem specifically asks for pairs and not the individual factors alone.
I hope you benefit from my explanation.
